• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Hello all..........
A few years ago(20045 I believe) there was a thread here in this forum regarding determining base offfset channel and steps for Motorola UHF and VHF trunking systems for use in scanners.
Within that post were several good pieces of information, including mentoion of an excel spreadsheet created by Brian Cathcart( AKA ScannerDude KE4PJMJ )who I am trying to contact so as to obtain a copy of same.
I am having trouble determining the correct Base Frequencies, Offset channels and Step for a Motorola UHF trunking system and feel this sheet would probably help. The system in question is the Motorola 9600 baud Common Air Interface Exclusive system, of Bergen County, NJ.
The older Uniden scanners ( Models BC796D and BC296D) require up to 3 sets of this information. I have run Unitrunker to find the channel numbers but they do not show up in the display as they are alleged to do.
Any and all assistance in figuring this out and finding a copy of Brian's spreadsheet will be much appreciated.
Thanks in advance and 73's

Please read your thread in the Unitrunker forum.

Again, the spreadsheets are for 3600/Type II systems. They are not for 9600/P25 Trunked systems; they 98% of the time announce the base and spacing table information so no calculations are needed. If you need to calculate then you're probably doing something wrong or misunderstanding the situation
